Fastest way to calculate the size of an file opened inside the code (PHP) -



Fastest way to calculate the size of an file opened inside the code (PHP) -

i know there quite bit of in-built functions available in php size of file, of them are: filesize, stat, ftell, etc.

my question lies around ftell quite interesting, returns integer value of file-pointer file.

is possible size of file using ftell function? if yes, tell me how?

scenario:

system (code) opens existing file mode "a" append contents. file pointer points end of line. system updates content file. system uses ftell calculate size of file.

fstat determines file size without acrobatics:

$f = fopen('file', 'r+'); $stat = fstat($f); $size = $stat['size'];

ftell can not used when file has been opened append("a") flag. also, have seek end of file fseek($f, 0, seek_end) first.

php file filesize

ios - Fragment Shader GLSL for texture, color and texture/color - i want accomplish glsl shader, can texture , color vertex objects. in fact, works me in 2 3 cases: 1) if have texture assigned (but no specific color - color "white"), textured object - works 2) if have texture , color assigned, textured object modulated color - works 3) if have color assigned no texture, black object - doesn't work my shader looks this: varying lowp vec4 colorvarying; varying mediump vec2 texcoordvarying; uniform sampler2d texture; void main(){ gl_fragcolor = texture2d(texture, texcoordvarying) * colorvarying; } i guess that, texture2d(...,...) returns 0 if no texture assigned - seems problem. there way in glsl can check, if no texture assigned (in case, want gl_fragcolor = colorvarying;) "if" isn't alternative in glsl shader, if understanded correctly - ideas accomplish this? or necessary create 2 different shaders both cases? like i'd ...

c# - Can ProtoBuf-Net deserialize to a flat class? - protobuf-net uses nested protobuf constructs back upwards inheritance. however, can made force properties flat target class has same properties inherited "serialized" version? see test illustration below. needless result of flat namespace null both properties. possible solution: re-create info flat.b first on property property basis. note: not prefered option. using system; namespace hierarchy { using protobuf; [protocontract] public class { [protomember(1)] public string prop1 { get; set; } } [protocontract] public class b : { public b() { } [protomember(1)] public string prop2 { get; set; } public override string tostring() { homecoming "prop1=" + prop1 + ", prop2=" + prop2; } } } namespace flat { using protobuf; [protocontract] p...
